OIL CONTAINER.

f To all lwhom t may conce/m.'

Be it known that I, EDWARD G. THOMAS,

a citizen of the United States, residing at Toledo, in the county of Lucas and State n of Ohio, have invented certain new and useful Improvements in Oil Containers, of which the following is a specification.

This invention relates to oil containers, and particularly to containers for holding oil in position so that the working parts of mechanisms are immersed therein.

When machines such as weighing scales are used in an atmosphere where they are liable to corrosion, it is sometimes desirable la 'to keep some of the working parts immersed in oil. The check link pivots of weighing scales are, for example, sometimes thus subjected to corrosion when the scales are used in crcameries. 2o It is one of the objects of my invention i to provide means for keeping check link pivots or other mechanical parts immersed in oil.

Another object ofthe invention is to provide a container for oil having means for automatically draining oil water or brine which may accumulate in the bottom of the container.

Other objects and advantages will be apparent from the following description, in which reference is had to the accompanying drawings illustrating preferred embodiments of my invention and wherein similar reference numerals designate similar parts throughout the several views.

In the drawings Figure 1 is an elevational view of the scale in which my invention has been incorporated, parts being broken away in order to better illustrate the invention;

Figure 2 is a detail sectional View on an enlarged scale of the form of receptacle shown in Figure 1; and

Figure 3 is a fragmentary detail View showing a modified form of receptacle.

Referring to the drawings in detail, and particularly to Figures 1 and 2, the base 1 of the scale shown in the drawings supports adjacent one of its ends an upright housing 2 which contains the load-offsetting mechanism (not shown). Adjacent its other end the base V1 supports a base horn or fulcrum stand 3, and the fulcrum stand in turn su ports a lever 4, the nose of which exten s into the housing 2, where it is connected to the load-offsetting mechanism.

The oommodity-receiver of the scale illustrated consists'ofva platter 5 carried by a spider 6 which is pivotally supportedin the usual manner by the lever 4. The platter is held in horizontal position during wei hing movements of the lever by'means o a spider stem 'l' and a check link 8, the spider stem extending downwardly through the hase l and having a pivotal connection with one end of the link 8, the other end of the link being connected to the lower end of a shift post 9.

In order that the scale may weigh correctly Withoutregard to the position of the load on the platform, it lis necessary that the fulcrum and load pivots on thelever 4 and the pivots at .the end of the check link 8 lie at corners of a parallelogram. It is also necessary that the pivots operate without friction. When scales of this type are used in creameries, the presence of salt and moisture is liable to result in rapid corrosion of the pivots, and this corrosion is especially detrimental to the pivots of the check link, as it causes friction inthe operation of the scale and wear, which destroys the parallelogrammatic relation of the check link and lever pivots. I have, therefore, provided a receptacle -for the check link mechanism which is adapted to contain oil so that the check link pivots are submerged and thus protected from the action of salt and water.

The receptacle 10 is secured to the under side of the base 1 by means of a screw 11, and. forms a protective housing for the check link mechanism, as well as a receptacle for oil. Owing to the fact that some of the moisture which condenses upon the spider stem and other parts may find its way into the oil and because water may trickle into f it when the scale is being Washed, I have provided a passage 12 leading from the lower pai-t of the interior of the receptacle and extending upwardly outside thereof to a level somewhat below that of the top of the receptacle. When water enters the receptacle it sinks to the bottom and, were it not for the provision of the passage 12, the oil flowing on top of the water would, as the level of the water rose, flow over the top and would eventually be entirely replaced by Water. By reason of the fact that the passage l2 leads from adjacent the bottom of the receptacle to a level below its top, the discharge of the Huid in the loiverpart of the receptacle-that is. the Water-is insured and the upper surface oit the oil surrounding' the check link remains at the level of the upper end of the passage l2.

In the form of the device shown in Figures l and 2 the passage 12 is formed integrally with the receptacle7 the opening from the passage into the interior olf the receptacle being` drilled and the hole in the outer Wall ot the passage through which the opening into the receptacle ivas drilled being closed by a screiv plug 13.

In the form shown in Figure the re ceptacle l0 is itormed Without the. passage and the passage l2 consists ot a bent tube. one arm of ivhich extends horizontall;v into an opening `in the receptacle and is secured therein, While the other arm extends upivardlj7 to a level somewhat beloiv that of the top of the receptacle. The opera tion oi the form shoivn in Figure is substantiall;T the same as that of the forni shoivn in Figures l and 2.

lllhile it will be apparent that the illustrated embodiments of my invention herein disclosed are ivell calculated to adeqiuitelj.v fuliill the objects primarilyv stated it is to be understood that the invention is su.cig ceptible to variation, modiiication and change Wit-hin the spirit and scope of the subjoined claims.

I-Iaving described my invention, I claim:

l. In a Weighing scale. in combination, a

base, check link mechanism located below said base, and a receptacle surrounding said check link mechanism and adapted to hold oil.

In a Weighing scale. in combination, a base, check link mechanism located below said base, receptacle. means for securing; said receptacle in position to retain oil about said check link mechanism, and means 'for automaticallv discharginer surplus liquid iliroin the loiver part ol: said receptaclev` whereby the `liruid retained in said receptacle is prevented from tlowin;r over the upper educ o' said receptacle.

3. In a iveigzhin; scale. in combination. a base. chr-cls link mecha. .sin located beloiv said base. a receptacle. means 'tor securing said receptacle in poiffii'ion to retain oil about said check link mechanism. and a passage leadingT from the interior olE said receptacle :uljacent the 1nottoin thercot to a level beloiv the level ot' the top of said receptacle.

l. In a Weighing' scale. in combination. a base. check linl; mechanism located below said base. a receptacle sin'roundingg said check link mechanism and adapted to hold oil in position in ivhich. said check link mechanism is ii niersed therein. and a passage leadingr from ivitliin said receptacle adjacent the bottom thereof upwardly exterioilj." of said receptacle and to a level below the top ot said receptacle.
